Context aware services for smart learning environments
(2009)This thesis describes a cost-effective infrastructure and implementation for building ubiquitous learning spaces. It uses techniques from the semantic web and ubiquitous computing to build a learner-centric service-based ... -
Defending against false data injection attacks in power systems: techniques for securing state estimation and distance protection
(2025)The digitalization of power systems—enabled by technologies such as digital substations and Wide-Area Monitoring, Protection, and Control (WAMPAC) systems—has improved automation, visibility, and system control. However, ... -
Estimation and detection theory in visible light communication systems: a perspective on realistic receivers
(2024)Visible light communications (VLC) has been proposed as a promising way for nextgeneration wireless communication networks to mitigate the scarcity of the radio frequency (RF) spectrum, and has consequently attracted ... -
Robust channel estimation, localization, and tracking in visible light systems under signal-dependent noise
(2025)Visible Light Communication (VLC) is an emerging wireless technology that employs light-emitting diodes (LEDs) or lasers to transmit data over the visible light spectrum. Due to its inherent advantages, such as license-free ... -
Steady state analysis of oscillators
(2010)A common method used for steady-state analysis of oscillators is called Harmonic Balance. Harmonic balance finds the steady-state solution directly in frequency-domain. However, Harmonic Balance is very sensitive to the ... -
Transformerless current source converter-based battery energy storage systems
(2025)Conventional battery energy storage systems (BESSs) connected to medium-voltage ac grids, whether integrated with renewable energy sources (RESs) or used in battery charging applications, face several challenges, including ...
